    • Centimeter-Sized Monolayer CVD Graphene with High Power Factor for Scalable Thermoelectric Applications 

      Schrade, Matthias; Xing, Wen; Thorshaug, Knut; Belle, Branson (Peer reviewed; Journal article, 2022)
      Among the many extraordinary qualities of graphene, its thermoelectric properties have attracted significant interest, for example, in active cooling applications. Here, we report on the thermoelectric transport properties ...

    • Factors Determining Microporous Material Stability in Water: The Curious Case of SAPO-37 

      Kalantzopoulos, Georgios N.; Lundvall, Fredrik; Thorshaug, Knut; Lind, Anna Maria; Vajeeston, Ponniah; Dovgaliuk, Iurii; Arstad, Bjørnar; Wragg, David; Fjellvåg, Helmer (Peer reviewed; Journal article, 2020)
      Silicoaluminophosphates (SAPOs) are a special class of zeolites that, due to their acidic and shape-selective properties, play a major role in ion exchange and separation processes and in crude oil cracking. SAPO-37 has ...

    • Graphene oxide-based silico-phosphate composite films for optical limiting of ultrashort near-infrared laser pulses 

      Petris, Adrian; Vasiliu, Ileana Cristina; Gheorghe, Petronela; Iordache, Ana Maria; Ionel, Laura; Rusen, Laurentiu; Iordache, Stefan; Elisa, Mihai; Trusca, Roxana; Ulieru, Dumitru; Etemadi, Samaneh; Wendelbo, Rune; Yang, Juan; Thorshaug, Knut (Peer reviewed; Journal article, 2020)
      The development of graphene-based materials for optical limiting functionality is an active field of research. Optical limiting for femtosecond laser pulses in the infrared-B (IR-B) (1.4–3 μm) spectral domain has been ...

    • In-situ XRD studies of dolomite based CO2 sorbents 

      Arstad, Bjørnar; Lind, Anna Maria; Andreassen, Kari Anne; Pierchala, Joanna; Thorshaug, Knut; Blom, Richard (Peer reviewed; Journal article, 2014)
      Calcined dolomite (a CaOMgO material derivative of the natural mineral dolomite) has the potential as a CO2 sorbent working at high temperatures (500-650 °C) in processes like post combustion carbonate-looping, or in sorbent ...

    • Structural changes in SAPO-34 due to hydrothermal treatment. A NMR, XRD, and DRIFTS study 

      Arstad, Bjørnar; Lind, Anna Maria; Cavka, Jasmina Hafizovic; Thorshaug, Knut; Akporiaye, Duncan; Wragg, David; Fjellvåg, Helmer; Grønvold, Arne; Fuglerud, Terje (Peer reviewed; Journal article, 2016)
      When SAPO-34 is used as an industrial MTO catalyst, structural transformations leading to permanent deactivation are inevitable. The performance loss is linked principally to a redistribution of Si in the material, leading ...

    • Zeolite surface methoxy groups as key intermediates in the stepwise conversion of methane to methanol 

      Dyballa, Michael Martin; Thorshaug, Knut; Pappas, Dimitrios; Borfecchia, Elisa; Kvande, Karoline; Bordiga, Silvia; Berlier, Gloria; Lazzarini, Andrea; Olsbye, Unni; Beato, Pablo; Svelle, Stian; Arstad, Bjørnar (Journal article; Peer reviewed, 2019)
      This contribution clarifies the overoxidation-preventing key step in the methane-to-methanol (MTM) conversion over copper mordenite zeolites. We followed the methane-to-methanol conversion over copper mordenite zeolites ...
